This project supports efforts to eliminate malaria and other interventions. Your mapping contribution will help prevent the suffering and loss of life this disease causes!

HOT and DigitalGlobe have teamed up to identify and map populated places in an area of interest covering over 500,000 square kilometers in Southern Africa, Southeast Asia and Central America to support the Clinton Health Access Initiative's malaria program.

This project is to trace buildings in this region of Zimbabwe. Please use the Imagery provided by DigitalGlobe's Maps API Premium Imagery (it should load automatically in the iD and JOSM editors). This imagery may be offset, see instructions for details.

Project Specific Mapping Notes

Some of these squares may already be partially or fully mapped, please review and map missing features if needed, fix up the existing mapping, or just mark it "Done" if already complete.

Imagery Notes

Please use the imagery provided by DigitalGlobe's Maps API Premium Imagery as it is often newer than Bing or Mapbox, however, it is often offset; align it to existing features or GPS traces where applicable, if no GPS available, use Bing imagery as best alignment.

If the imagery does not load, use this TMS service: https://api.mapbox.com/v4/digitalglobe.2lnp1jee/{z}/{x}/{y}.png?access_token=pk.eyJ1IjoiZGlnaXRhbGdsb2JlIiwiYSI6ImNpd3A2OTAwODAwNGUyenFuNTkyZjRkeWsifQ.Y44JcpYP9gXsZD3p5KBZbA

Buildings

Please accurately outline all the buildings you can find. The outline should be for the full size of the building even if it is partly covered by trees in the imagery.

Most buildings are rectangular, after drawing the outline, use the 's' key in the iD web editor to "square" the corners.

For circular buildings there is the 'o' key in the iD editor to create a circular structure.

Many buildings are very close, but do not actually touch each other, try to map them close to each other without letting them connect or share nodes with each other, roads or residential area outlines. In the iD web editor, holding down the "alt" key will keep nodes of "snapping" to each other and accidentally connecting.

In the iD web editor, the first time you map a building you will use the "Building Features" category and then at the top of the list select "Building" again, this is the most generic building tag we can use as we almost never can tell the more specific use of any building from imagery alone.

If you have personal knowledge of a building, please add that information to the building, like the name or type of building (hospital, school, gas station, etc)

Roads and Other Features

Your are not requested to map anything other than buildings in this project, however if you choose to, please consult Highway Tag Africa Wiki for details and examples of mapping roads in Africa and the broader OSM Wiki for mapping and tagging guidance.
